Crowdfunding platforms can be the last refuge of a desperate entrepreneur or the go-to market strategy for an appealing consumer product. When a product does well, it does really well, smashing records and even outstripping its own ability to deliver on the goods. When it does badly, well, it often fades away, or at least the company realizes that D2C might not be their best channel.

The app is designed for iPhone 4S and select Android devices, connects via Bluetooth, and has social features to compete with friends and earn points, and the system will have an open source SDK. The bracelet and shoe clip are completely waterproof, although it’s unclear
